Calculate the LCM of 986,254,638,938

Given numbers are 986,254,638,938

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 986,254,638,938 is 646020298.

Find LCM of 986,254,638,938 with Prime Factorization


2 986, 254, 638, 938
29 493, 127, 319, 469
17, 127, 11, 469

Multiply the prime numbers at the bottom and the left side.

2 x 29 x 17 x 127 x 11 x 469 = 646020298

Therefore, the lowest common multiple of 986,254,638,938 is 646020298.

LCM Formula to Find Lowest Common Multiple of 986,254,638,938

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

986 x 254 x 638 x 938 = 149876709136

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

986 : 1, 2, 17, 29, 34, 58, 493, 986

254 : 1, 2, 127, 254

638 : 1, 2, 11, 22, 29, 58, 319, 638

938 : 1, 2, 7, 14, 67, 134, 469, 938

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 986,254,638,938, is 2.

Now, the common factors can be found like this.

986:2x 17x 29

254:2x 127

638:2x 11x 29

938:2x 7x 67

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 29 = 116

Therefore, the value for common factors is 116.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 149876709136/(2x116)

LCM = 149876709136/232

LCM = 646020298

Thus, we can understand that the LCM of 986,254,638,938 is 646020298.
